IMAP

http://docs.python.org/library/imaplib.html imaplib — IMAP4 protocol client

import getpass, imaplib

#M = imaplib.IMAP4()
M = imaplib.IMAP4('localhost', 143)
#M.login(getpass.getuser(), getpass.getpass())
M.login('patrick', 'password')
M.select()
typ, data = M.search(None, 'ALL')

SMTP

Sample - Standard SMTP (Apache James)

This will work with the default install of ../../james/install, Apache - James.

import smtplib

def mail(serverURL=None, sender='', to='', subject='', text=''):
    """
    Usage:
    mail('somemailserver.com', 'me@example.com', 'someone@example.com', 'test', 'This is a test')
    """
    headers = "From: %s\r\nTo: %s\r\nSubject: %s\r\n\r\n" % (sender, to, subject)
    message = headers + text
    mail_server = smtplib.SMTP(serverURL)
    mail_server.sendmail(sender, to, message)
    mail_server.quit()

mail('localhost', 'patrick@localhost', 'trac@localhost', 'Help!', 'Please help me...')

Note: I think the to parameter is a list of email addresses e.g:

recipients = [
    'me@mail.com',
    'me@mycompany.com',
    ]

Sample - Google (GMail) SMTP

mail_server = smtplib.SMTP('smtp.gmail.com', 587)
mail_server.ehlo()
mail_server.starttls()
mail_server.ehlo()
mail_server.login('gmail-user-name', 'gmail-password')

Testing

Send

For testing purposes only… we can use sockets:

# From:
# http://pleac.sourceforge.net/pleac_python/sockets.html
# Example: Connect to a server (tcp)
# For real applications you should use smtplib.

import socket
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect(("cluster3.eu.messagelabs.com", 25)) # SMTP
print s.recv(1024)
s.send("mail from: <me@mycompany.com>\n")
print s.recv(1024)
s.send("rcpt to: me@mycompany.com\n")
print s.recv(1024)
s.send("data\n")
print s.recv(1024)
s.send("From: Python Lover\nSubject: Python is better then perl\n\nYES!\n.\n")
print s.recv(1024)
s.close()

Server

http://code.djangoproject.com/changeset/9793 Django, Changeset 9793

The easiest way to test your project’s use of e-mail is to use a “dumb” e-mail server that receives the e-mails locally and displays them to the terminal, but does not actually send anything. Python has a built-in way to accomplish this with a single command:

python -m smtpd -n -c DebuggingServer localhost:1025

Note: Also see the testing section in Links.
